Short-circuit Protection

Main output power shall latch into shut down state within 50ms when short circuit applied

This product incorporates multiple 12V rails over current protection. If you let many peripherals consume the power on only one 12V rail, it may trigger the over current protection and shut down the system. Please re-direct certain peripheral power cable to other 12V rail to share the current loading to ensure highest stability and safety.

Notice：If you plan to put in 2 or more high end, power demanding GPU cards, please choose the motherboard that comes with extra 4P Molex/ 4P FDD / 6P PCI-E power socket(s) on board and connect them with your power supply. This will prevent the motherboard from overloading and possibly causing damage to your system including your power supply. The damage to the motherboard and the power supply caused by failing to do the above instruction will not be covered under Lepa manufacturer’s warranty. Please refer to your motherboard’s user manual to configure your system properly to prevent damage to your system and your power supply.

Please only use the modular cable provided in your LEPA power supply package. Do NOT use other modular cables to prevent pin configuration damage to your system and your power supply
